The government-owned company is looking at ways to de-clutter Britain's mass of road signs, with trials of the 5G broadband system set to take place on the A2 and M2 between London and Dover later this year.

A report published by Highways England said a range of information including variable speed limits and warnings of traffic jams ahead would be transmitted to dashboard-mounted screens inside vehicles.

The system would also be able to warn drivers of roadworks so they could change lanes well in advance, potentially reducing the chance of traffic build-up at mergers, according to The Times.

During the initial trials, only specially equipped motors will be able to see the in-car information.

And vehicles may need to be fitted with a compatible screen if the system is permanently implemented in the future.

The road network operator hopes the system could improve driver awareness and safety, and even be used to provide future driverless cars with the information they need to operate on Britain's roads.
